Abstract

Hybrid solar cells based on a combination of conductive polymer poly (3,4-ethylenedioxyth1ophene) (PEDOT) doped with polystyrenesulfonate (PSS) and inorganic semiconductor CuIn(S,Se)₂ (CISSe) were investigated. The CuInSe₂ (CISe) absorber layers were electrodeposited on IT0 covered glasses from aqueous solutions with various ratios of elements. The ITO/In(O,S)/CISSe photovoltaic (PV) junctions were prepared by the sulfurization of ITO/CISe precursors at 450 °C in the H₂S atmosphere. A PEDOT-PSS layer of p-type is considered as an alternative for the traditional window top layer on the CISSe absorber layer in the cell structure. The polymer deposition was performed using spin-casting technique. The PV properties of the prepared ITO/In(O,S)/CISSe and ITO/In(O,S)/CISSe/PEDOT- PSS structures were investigated, with special attention paid to the role of the conductive polymer layer in the cell structure.
